FIRE-PROOF SHUTTER.

SPECIFICATION forming part of Letters Patent No. 320,974, dated June 30,1885.

Application filed February lfl, 1385. (No model.)

T 0 all whom it may concern.-

Be it known that 1, CHARLES C. ScHREIBER, a resident of Cincinnati, inthe county of Hamilton and State of Ohio, have invented certain new anduseful Improvements in Fire- Proof Shutters, of which the following is aspecification.

The several features of my invention and their use conjointly orotherwise will be apparent from the following description.

In the accompanying drawings, Figure 1 shows in elevation a windowprovided with my improved form of shutter. Fig. 2 shows in elevation theframe of the shutterdivested of its cover or sheathing, and also showsparts of the window-fra1ne. Fig. 3 is a top view of the shutter inposition in a window, the top portion of the window being broken away.Fig. 4 is a top view of the hinge-end portion of the shutter in positionin the window, the top portion of said window being broken away.

The shutter is made in two similar halves usually, and by preference;but for narrow windows a single shutter may be used. The shutter isarranged in segments which close into each other, or telescope together,as is sometimes said. The frame-work on which the shutter is builtconsists of the vertical rods A, united by meansoflazy-tongs B at topand bottom. The diagonal rods bb, which make up the tongs B, arearrangedin pairs, in which the two rods cross each other at theircenters, and are there pivoted together. The ends of the rods 1) b arepivoted to the ends of the rods b b of the adjoining pairs, and thepivots b, which make these joints, are prolonged on each side into thechannels a of the rods A. Now, when the rods A are pulled apart, thepivots I) slide in the channels a, and the rods A separate, keeping atequal distances apart and maintaining their parallelism.

From the top and the bottom of the windowsash flat bars 0 0 project, andthey fit between the two sets of vertical bars A, serving as guides forthe shutter to run on,and at the same time holding the shutter inposition.

The forward or loose end of the shutter preferably rests directly upon aroller or rollers, as D. This roller is usually placed, as shown,between a pair of the vertical bars A. The roller facilitates thesliding of the shutter.

As shown in Figs. 2 and 4, the bars 0 O are out diagonally across,forming the short piece 0 at each end. From the short piece 0 lugs 0project into the casing and form the preferred axis or means on whichthe shutter turns. When the bars A are forced close together, their endsare all on the short pieces 0 above and below, and the collapsed ortelescoped shutters may now be rotated on thelugs O and opened, so thatonly its width obstructs the light of the window.

On each side of this frame-work leaves or panels of metal, preferablysheet-iron, are placed. The first leaf,E,is placed fiat against thefirst rods A; the second leaf, E", is attached to the next rod A, but isset out far enough from it to permit the first leaf, which its edgeoverlaps, to slide under it; and so the remaining leaves, as E E", areplaced, each one set out a little farther than the preceding one.

When the frame is closed, the leaves close with it, and thus telescopethe shutter into small dimensions. It can now be turned aside, owing tothe cut in the bars 0 O,and does not project beyond the face ofthe wall,and at the same time clear opening of the window isencroached upon onlyby the thickness of the shutter.

The frame maybe sheathed on one or both sides, the latter being thepreferable form, as it forms an air-space between the two metallicplates, which makes the shutter much more nearly fire-proof.

Some difficulty has been experienced in having the plates on each sideextend clear to the wall, and still allow the shutter to be swingingopen. This difficulty has been met by the arrangement shown in Figs. 3and 4. The inner plate, E, of the outer sheathing is made short, so thatit does not quite reach the wall when the shutter is closed,and clearsthe wall when the shutter is thrown open. A narrow plate, F, extendsfrom the wall just over the edge of this inner plate and immediately infront of it, so that it serves to close over the break made by theshortening of this outer plate, and when the shutter is opened it comesin contact or nearly in contact with the face of the plate, as shown bythe position of the shutter in Fig. 4.

The joint or point of junction between the inner plate, A, and thewindow frame may be made tight by a vertical strip, F, attached to thewindow-frame, and so located that when the shutter is extended, as shownin Fig. 3, the strip comes inside of and overlaps this inner plate, E

The overlapping edges of each plate, since they do not slide under theadjoining plate, may be ornamented by a bead or similar design.

WVhile the various features of my invention are preferably employedtogether, one or more of them may be employed without the remainder. Inso far as applicable one or more of said features may be employed inconnection with folding or extension shutters or gates other than theone particularly herein specified.

What I claim as new, and desire to secure by Letters Patent, is

1. The vertical rods A, arranged in pairs, each rod carrying agroove orchannel, a, and the lazy-tongs located between the rods A of a pair, thepins b ofsaid tongs being prolonged on each side of said tongs andlocated and working in their respective grooves, and the leaves, as E EE E, secured to said vertical rods, and each leaf, respectively, passingunder or over its adjacent leaf, substantially as and for the purposesspecified.

2. The vertical rods A, arranged in pairs,

and provided with grooves or channels a, and the lazy-tongs locatedbetween the rods A of a pair, the pins 1; of said tongs located andworking in said grooves a, and the leaves, as E E secured to saidvertical rods on the outer side of the latter, and each leaf s1idingalongside of its adjacent leaf, substantially as and for the purposesspecified.

3. The vertical rods A, arranged in pairs, each rod carrying a groove orchannel, a, and the lazy-tongs located between the rods A of each pair,the pins 1) of said tongs located and workingin said grooves a,and theleaves, as E E 13 E, secured to said vertical rods, each leaf passingalongside of its adjacent leaf, and the upper and lower guide-bars, G 0,respectively located between ends of 0pposing vertical rods A,substantially as and for the purposes specified.

4. The collapsing frame consisting of rods A and tongs B, in combinationwith theguidebars 0 0, having detached short end pieces, 0 provided withaxial lugs 0 substantially as and for the purposes specified.

5. The piece F, in combination with leaves on a collapsing sheathedhinged shutter, substantially as and for the purposes specified.
